++ + - -- - increase or decrease the amplitude of the traces in the active trace-group
|><| |<>| - decrease or increase the width of the time window for the traces in the active trace-group
<< < > >> - shift the time window to the left or right

Lock Alignment button - toggles locking of current trace-group time alignment (see: Main Menubar -> View -> Lock Alignment)
Align Amplitude to Window button - align amplitude range of each trace groups to the min/max amplitude in current time window (see: Main Menubar -> Align Amp to -> Window)
Full Window button - toggles display of the active trace in the full SeisGram2K window (see: Main Menubar -> View -> Full Window)
SG2K button - launches active trace-group in a new SeisGram2K window (see: Main Menubar -> View -> New SG2K Window)

RemoveMean button (*) - calculate and remove the mean value of each trace
Integrate button (*) - integrate each trace in time domain
Differentiate button (*) - differentiate each trace in time domain
RemoveGain button - remove gain by dividing amplitudes by sensitivity if available in trace header or response file
